| 锂离子电池已成为现代生活各方面储能系统的重要组成部分，随着经济和社会的持续发展，人们迫切期待新一代高能量密度锂离子电池。硅基负极因拥有较高的能量密度与丰富的自然资源储量而备受关注，然而，硅基负极体积膨胀问题突出且电极/电解质界面不稳定，导致其安全性差、循环稳定性不理想，严重阻碍了其商业化应用。近年来，醚类电解质在高性能锂离子电池中得到广泛的研究，普遍思路是通过醚类电解液体系构建稳定界面以提升硅基负极的性能。全面综述了醚类电解质的组分设计要求（包括锂盐、添加剂、溶剂）、线性醚与环状醚的作用机制，以及醚类电解液体系在提升负极界面稳定性与循环稳定性方面的研究成果；最后对新型醚类电解液的设计策略与面临挑战进行了展望。 |

| Lithium-ion batteries have become an important part of the energy storage systems in all aspects of modern life. With the continuous development of the economy and society, a new generation of high energy density lithium-ion batteries is highly anticipated. Silicon-based anodes have attracted much attention because of their high energy density and abundant natural reserves. However, the severe volume expansion and unstable electrode/electrolyte interface of silicon-based anodes have led to poor safety and unsatisfactory cycling stability, which has seriously hindered their commercial application. In recent years, ether electrolytes have been widely studied in high-performance lithium-ion batteries, and a common strategy is to enhance the performance of silicon-based anodes by constructing a stable interface through ether electrolyte systems. Therefore, this paper provides a comprehensive overview of the component design requirements of ether electrolytes, including lithium salts, additives, and solvents, the mechanisms of linear ethers and cyclic ethers, as well as the research results of ether electrolyte systems in improving the anode interfacial stability and cycling stability. Finally, an outlook on the design strategies and challenges of new ether electrolytes is provided. |
